i0 @ZZ wtont it may concern:

Be it known that we, ROBERT IV. GIBSON, a resident of Palestine, in the county of Anderson and State of Texas, and VILLIAM N. BEST, a resident of Los Angeles, in the county of Los Angeles and State of California, citizens of the United States, have invented new and useful Improvements in Pneumatic Sand- Flue and Netting Cleaners, of which the following is a specification.

Our invention relates toan improvement in pneumatic sand-flue and netting cleaners; and the object is toV provide portable means for blowing sand through locomotive Iiues and nettings when coal-burners are employed for the purpose of cleaning said iiues or nettings; and with this object in view our invention consists in certain novel features of construction and combinations of parts,which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a view in sidel elevation. Fig. 2 is a front end elevation. Fig. is a rear elevation, and Fig. Je is a det-ail.

A represents the sand-receptacle, havinga cover B at the top, which is removable when, it is desired to replenish the sand-receptacle.Y

G denotes a handle at the front end of the receptacle, by means of which the cleaner is manipulated, and P P indicate legs upon.

which the device is adapted to rest, these legs being secured to the under sidel ofthe receptacle, as at O O. The forward end of the bottom is in a lower plane than the rear end, these two portions being connected by an inclining portion o, so that gravity lends its aid to cause the sand contained in the receptacle to descend to the lower plane ofthe forward end. An openingD is formed in this lower portion of the bottom, preferably at a point adjacent to the inclining portion a, so that the sand descending over this incline naturally finds ready escape through this opening D. A slide-valve C, fitted in guide- Ways C', controls this outlet D, and it is provided with a stem E, which slides through a gland F and is provided with a handle F', by which the valve is slid back and forth to regudoor-passage.V `and afterward the stop-valve C of the sand late the size'ofthe outlet, either to entirely open or close it or to vary the size of the opening according to the requirements in the operation of the device. From the opening D a pipe M leads downwardly and connects with an elbow L, and the latter is coupled to a discharge-pipe' N and has within it the injectornozzle K. Air-hose II is attached tothe discharge-pipe by means of a pipe connection I, and in theV latter the' stop-cock .I is arranged to control the Yair-supply through the hose and nozzle. Of course it is understood that the other end of the hose is attached to the pipe connection of the air-pipe leading to the reservoir ofthe locomotive. This connection, however, forms no part'of the invention, and consequently is not shown. It is obvious that steam might be employed instead of air. The passage of either air or steam'through the hose I-I, connection I, and discharge-pipe N creates a suction in the injector-nozzle K, drawing sand down from the reservoir above into the elbow L, after Whichn the pressure of air or steam, as thecase may be, discharges this steam under pressure at the point or points where it is to be used.

To use the device,the furnace-door is opened and the discharge-pipe is placed through the The air-.cock is then opened box or receptacle, and, as just explained, the action or passage of the air or steam through the pipes will cause the sand to be forced to the end or mouth of the i'lues to be cleaned. The discharge-pipe will be regulated by the operator, so that the sand will tlow to the end or mouth of the iiues, whereupon the current caused by the flow of air or steam from the injector-nozzle will carry it through all the tiues and clean them, and if coal-burners are used the netting will likewise be cleaned. It is understood, of course, that oil-burning locomotives do not have nettings. In this way the flues and nettings, if the latter are used, are easily, quickly, and thoroughlycleaned and put in good order for effectual service.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of our invention, and hence We do not Wish to limit ourselves to the exact construction herein set forth; but,

Having fully described our invention, what We claim as new, and desire to secure by Letters Patent, is-

l. A sand-nue and netting cleaner, comprising a sand-receptacle, a discharge-pipe, a pipe leading from the receptacle to the discharge -pipe and connecting said parts together for conducting sand to the dischargepipe, an injector-nozzle, and means for -controlling the discharges through said parts.

2. A sand-flue and netting cleaner, consisting of a sand-receptacle having an opening in its bottom, an injector-nozzle, a pipe leading from the opening in the receptacle, to the nozzle, a valve for controlling said opening for the discharge of sand, an air or steam supply hose or pipe and a valve or stop-cock for regulating a passage of air or steam therethrough.

3. The combination with a sand-receptacle having an opening in its bottom, a pipe leading therefrom, a valve and means for controlling the movements of said valve, of an injector-nozzle to which said pipe leads, a discharge-pipe leading from said injector-nozzle, an air or steam supply pipe and a stop-cock for controlling the passage of air or steam therethrough.

4. The combination with a sand-receptacle, the bottom of which is in two planes with au inclining portion leading from one to the other, the lower plane of the bottom having an opening therein, a valve for controlling said opening, and a pipe leading therefrom, of an injector-nozzle to which said pipe leads, a discharge-pipe leading from said injector-nozzle, a hose, a connection between said hose and injector-nozzle, and a stop-cock in said connection for regulating the supply or passage of air or steam therethrough.

5. A portable sand-fine and netting cleaner comprising a sand-flue receptacle, a dischargepipe, and injector-nozzle, all connected together, and a valve for controlling the discharge from the receptacle to the injector- A
